1. Description
2. Operation
The “Guillotine type” cutter module is provided in
which the lower blade is fi xed while the upper blade
moves up and down to cut the paper perpendicularly
to the traveling direction.
The rotating motion of the DC motor is transformed
into the reciprocating motion of the upper blade by
means of the eccentric shaft.
A sensor is provided at the top dead center of the
blade stroke, which works to apply the brake on the
blade movement at every reciprocating cycle to make
it stop.
3. Operation of Each Part
1. Cutter Home Position Sensor
<Operation>
Cutter HP sensor detects the blade positions
by sensing the light-blocking plate linked to the
movement of rotary blade by means of the photo-
micro sensor.
